which version of windows are you using ?
Sounds like a typical windows 10 bug.
Given that windows 10 has more bugs than working compoonents.
Try using windows 7 - 100% stable and easier to shut off updates - the prime cause of buggering things up.
If you have to use a microsoft app store app (always dodgy) then try and get windows 8 - NOT 8.1
The app store runs happily on 8, but causes a lot of issues in 8.1 and 10.

Sounds like you've covered any hardware issues, so the most likely cause would be software and windows 10 is currently the most unstable os on the planet.
